Could rain trigger a volcano’s blast?
Monitoring rainfall may help predict when the world’s most dangerous volcanoes are about to erupt. Volcanologists have discovered that heavy rain can trigger the most dangerous type of eruption, called a dome collapse, which has caused most of the volcano-related deaths in the past 100 years.

Rebellische Ameisen erwartet der Tod
Nicht alle Ameisen haben Königinnen: Der in Südamerika vorkommenden Art Dinoponera quadriceps fehlt die Herrscherkaste. Stattdessen schwingt sich in dem hierarchisch organisierten, rund 80 Arbeiterinnen umfassenden Volk ein Alpha-Weibchen zur allein fortpflanzungsfähigen Anführerin auf, was jedoch oft zu tödlichen Streitereien führt.

NASA Study Finds Rapid Changes In Earth's Polar Ice Sheets
ONCE AGAIN "Earth's polar ice sheets are changing over relatively short time scales, that is, decades versus thousands of years," Rignot said. Thomas added that today's more precise, widespread measurements tell us rapid changes are common. "These observations run counter to much accepted wisdom about ice sheets, which, lacking modern observational capabilities, was largely based on 'steady-state' assumptions," Thomas said.

Pole verändern sich im Zeitraffertempo
Die Eisdecke an den Polen verändert sich nach neuen Erkenntnissen der US-Raumfahrtbehörde Nasa schneller als bisher vermutet. Die Konsequenzen für das Weltklima und die Meeresspiegel sind nicht absehbar.

Geckos’ feet get sticky from static
US scientists have found the first experimental evidence that geckos use electrostatic forces - not capillary action - to walk safely across even very smooth ceilings. To compare the electrostatic and capillary theories, Kellar Autumn of Lewis and Clark College in Oregon and colleagues measured the shear forces exerted by geckos' toes on a variety of surfaces. The team's discovery that geckos employ Van der Waals forces in this way could now be exploited to develop a new generation of 'dry adhesives'
